CN-224214890-U - Correcting device for flange port alignment

Abstract

The utility model discloses a correction device for flange port alignment, which mainly comprises jackscrews, sliding support rods, a base, positioning pins, support rod fixing screws, oil grooves and positioning pin supports. Due to the influence of various factors such as welding, installation, pipeline deformation, pipeline span length and the like, the two flange ports to be connected are often staggered, and are not aligned, such as axis deviation, angle deviation and the like. The traditional flange alignment method generally depends on manual adjustment, has low efficiency and difficult precision guarantee, sometimes needs to be forcedly aligned even by means of a large tool, is easy to damage a flange sealing surface, affects connection quality, and has certain potential safety hazards. Therefore, the correcting device with simple structure, convenient operation and capability of accurately and efficiently aligning the flange openings is designed, and can be used for a long time, so that the safety risk in the construction process is reduced, and the working efficiency is improved.

Description

Correcting device for flange port alignment Technical Field The utility model relates to the field of alignment correction after flange opening disassembly and inspection, in particular to a correction device for flange opening alignment. Background Flange connections are a common and important connection in industrial pipe installations and equipment connections. However, due to the influence of various factors such as welding, installation, pipeline deformation, pipeline span length and the like, misalignment and misalignment of two flange ports to be connected often occur, such as axis offset, angle deviation and the like. The traditional flange alignment method generally depends on manual adjustment, has low efficiency and difficult precision guarantee, sometimes needs to be forcedly aligned even by means of a large tool, is easy to damage a flange sealing surface, affects connection quality, and has certain potential safety hazards. Therefore, the correcting device which is simple in structure, convenient to operate and capable of accurately and efficiently aligning the flange openings is designed to have important practical significance. Disclosure of Invention The utility model aims to overcome the defects of the prior art, and provides the correcting device which has a simple structure, is convenient to operate, can effectively improve the alignment precision and efficiency of a flange opening, and can ensure the standardization of flange fastening in the correcting process. The utility model aims to achieve the purpose, and the correcting device for flange port alignment comprises a jackscrew (1), a sliding support rod (2), a base (3), a locating pin (4), a support rod fixing screw (5), an oil groove (6) and a locating pin support (7), wherein the jackscrew (1) is arranged on one side of the sliding support rod (2), the sliding support rod (2) is arranged in the base (3), the support rod fixing screw (5) is arranged at one end of the base (3), the oil groove (6) is arranged in the base (3), the locating pin support (7) is welded at one end of the base (3), and the locating pin (4) is arranged on the locating pin support (7). When the flange hole aligning correction device is used, the correction device for flange hole alignment is placed on the outer side of an offset flange hole, the positioning pin (4) is inserted into a flange hole, the positioning pin (4) can be replaced according to the size of the flange hole, the sliding support rod (2) is adjusted, the jackscrew (1) is adjusted to the outer side of the edge of another flange hole needing alignment, the support rod fixing screw (5) is screwed after the two flange holes are aligned, the sliding support rod (2) is fixed, the insertion bolt is used for fastening, the device is removed after the fastening is completed, and the bolts in the residual bolt holes are supplemented. Preferably, the upper part and the lower part of the base (3) are provided with oil grooves (6). Preferably, the sliding support rod (2) can slide relatively in the base (3), and oil grooves (6) are reserved on the upper side and the lower side in the base (3), so that the contact surface between the sliding support rod (2) and the base (3) is prevented from being corroded, and the relative sliding is prevented from being influenced. Preferably, in order to improve the supporting strength of the sliding support rod (2) and ensure that the strength of the offset flange is controlled in the recovery process, the contact surface of the sliding support rod (2) and the base (3) is designed to be arc-shaped, the bearing capacity of the contact area and torque is improved, and the larger flange can be adjusted. Preferably, the locating pin (4) is used for fixing a correction device for flange opening alignment, so that the device can not be fixed when the jackscrew (1) is forced.
